|Title: ||High intensity swimming outlay in Olympic distance triathlon does not affect cycling performance and cycling economy|
|Authors: ||Schiødt, Daniel|
|Issue Date: ||2010 |
|Abstract: ||Aim: The purpose of the present study was to investigate to what extent swimming at 100% of 500m velocity the first 500m of a 1500m swim will influence on average 1500m velocity and the intensity and economy during a 22.5km TT (time trial) on a cycle ergometer.
Method: Six triathletes (n = 6) five male and one female, age (34.8 ± 6.4) years,
and VO2max: (63.2 ± 5.7)ml*kg-1 * min-1), performed baseline testing on two different days: 1) an isolated 500m maximal swim test and a VO2max cycle test, 2) Cycle lactate threshold (LT) -, and a cycle 22.5km time trial test with continuous VO2max measurements. After resting for one day, two consecutive tests, separated by 24 hours, were performed: a) 500m maximal swimming outlay continued by 1000m swimming at competitive velocity (S500max TT), further continued by transition (T1) and a 22.5km cycle time trial (TT). b) 1500m swim at competitive velocity (S1500 TT), transition T1, and a 22.5km cycle TT.
Parameters (VO2, VO2 scaled, %VO2, VE, R, HR, La-, Brake power, CAD, Cc and WE) were measured.
Results: The results showed a significant difference (3.3%) between mean power produced during the 22.5km time trial and the S500max TT, accompanied by a 4% reduction in mean VO2 and a 2.5% increase in HR. No difference in mean power produced, VO2 or HR between the 22.5km TT and S1500 TT was apparent.
Conclusion: Although suffering from gradual fatigue and suspected hyperthermia in both consecutive tests, there were no significant differences in between S500max TT and S1500 TT. These triathletes may thus benefit strategically, and in an indirect manor physiologically, from a 500m maximal swimming outlay in an Olympic triathlon.
Advice: The advice to these triathletes is to implement a 500m maximal swimming outlay in their strategy in order to gain the best possible position for further benefits of drafting, and thereby maintaining the potential of optimizing their race performance in Olympic Triathlons.|
